Abstract
High speed flow finishing method has recently developed, which has an excellent performance for polishing an inner wall of stainless steel capillary D Present paper focuses on the finishing characteristics of the inner wall of stainless steel pipe with high speed flow finishing method D It is found that bar-type mandrel inserted into the hole of pipe has great performance in finishing, in which a diameter of mandrel is slightly smaller than inside diameter of the pipe D Experiments indicate that surface roughness of the inner wall of pipe decreases with the number of slurry flow pass D It is shown that both of larger grain size and higher concentration of the abrasive in water solvent, have a greater finishing rate of the pipe D. It is described that larger flow pressure of slurry yields greater surface roughness decrease D
